This project is carried out to build a salt taster that to detect the approximate level of salt contained in a liquid food. The three-level LED in this circuit is used as an indicator, that to differentiate the level of salt containing in food from the illumination of LED. The salt taster is created using a self-made probe which made from two metal sticks that cut from the paper clip as a detector to test the salt level in liquid. There are two experiments has been done to test on the functionality of salt taster, that is experiment testing on the salt solution that salt dissolved in distilled water. And, the next experiment was testing on the light Soya sauce with distilled water. In addition, examination of liquid food also has been done to obtain the test result. The three-level LED that are green LED, yellow LED and Red LED can be found in the circuit which represent the salt level where is low, normal and high respectively. Hence, when the probe is immersed into the liquid solution, the illumination of LED is indicated the salt level of the solution. A food experiment has been done that is noodles-in-cup of curry flavour and vegetable flavour were taken to be tested of its salt level. It was found that the two flavours of brand A and brand B is at normal salt level while brand C is at high salt level. When the test result is the illumination of red LED, it is means that the salt level is at high and ones should take caution of the intake of salt to prevent from illness.
